1. A nerve stimulator, comprising:
a mid-shell;
a stimulation acquisition module, the stimulation acquisition module comprising a stimulation and/or acquisition circuit and being mounted within the mid-shell;
a feed-through component, the feed-through component being disposed on an end surface of the mid-shell and being electrically connected to the stimulation acquisition module;
a mounting cover, the mounting cover being disposed on the end surface of the mid-shell and covering the feed-through component;
a flexible electrode comprising a first extension section and a second extension section, the first extension section being of a sheet structure and being provided with a proximal contact portion adapted to be electrically connected to the feed-through component, the second extension section being provided with a lead portion and a distal electrode site portion for applying electrical stimulation to a target tissue and/or recording a target tissue signal, the proximal contact portion and the distal electrode site portion being electrically connected to each other through the lead portion, the first extension section being provided between the mounting cover and the end surface of the mid-shell, the first extension section being connected to a side of the feed-through component that is facing toward the mounting cover, and the first extension section extending along the end surface of the mid-shell, and the second extension section protruding from a gap between the mounting cover and the mid-shell;
a pressure connector, the pressure connector being mounted to the mounting cover, the pressure connector applying a pressure on the flexible electrode in a direction toward the feed-through component, so as to allow the proximal contact portion of the flexible electrode to be electrically connected to the stimulation acquisition module through the feed-through component,
wherein the mounting cover is provided with a side edge extending toward a side surface of the mid-shell, the side edge and the side surface of the mid-shell form a channel for accommodating the flexible electrode, and the second extension section of the flexible electrode extends along the channel and extends out of the channel.
